Hey myvi3923,
You cannot directly associate physical hardware with a virtual machine - the PCI device must be able to map to a virtual device (e.g. a serial port) that XP mode supports.
They are a hardware that takes directly to the motherboard. When you use a Virtual Machine, it runs off a virtual motherboard and BIOS not your main motherboard. If you got a usb based devices it may work.
